Выдержка

F-Diazodiketones and F-vinyldiazoketons can experience reactions with both elimination and retention of diazogroup nitrogen producing useful fluoroalkyl-containing carbo- and heterocyclic compounds. On heating in benzene or toluene solutions (in the absence of any catalyst) fluoroalkyl-containing vinyldiazoketones undergo intramolecular cyclization to produce 3H-pyrazoles. Interaction of vinyldiazoketones with triphenylphosphine also proceeds with the retention of “dinitrogen” of diazogroup and gives rise with good yields to fluoroalkyl-containing 3,4,6-trisubstituted pyridazines by the way of tandem Staudinger and diaza-Wittig processes.
